Hi Mike,
I too find Anonymous users somewhat frustrating, but really not all that bad. GMM hasn't made it obvious how to change your name, so I don't blame people for being Anonymous. In the end, though, each is an individual account with stats, and unless you are a major mapper that I recognize, stats are all I look at. Yes, it's nice to know when I can trust a mapper more by just looking at the name, but most mappers that deserve that trust already have a name.
To cover you points:
- The stats tell you if they are doing bad edits, even on an Anonymous account. And if they are habitual offenders in my area, I can usually recognize them by their stats; as soon as I bring them up and see "342 edits since Feburary 2012, 67% approved" it is as much an identifier as a name.
- A lot of forum names don't match the Maps name. They are two different products, you can't force the names to match, unless you make them match their main Google account, which you just told Jax you don't agree should be revealed.
- Except for one bug I found, every time I've seen an account with zero stats approve an edit, it is a bot that has hundreds of thousands of reviews. I suppose it also be GRs with no edits also. Don't forget, reviews don't show in the pop-up.
- I'll agree with this, but again you can treat an Anonymous account just like one with a name; how are they really different? I have a very polite copy and paste I put in for these situations, usually people respond with "Ops, sorry, didn't realize; I'll undo!"
I will completely agree with you on your added on message, being able to address someone by there name is an important conflict avoidance/resolution technique. But I think the flip side is the number of people that will quit mapping if they have to reveal their name. I meet more people who are worried about revealing anything on the internet than the opposite way; none of them will map if you make them reveal their name. I'm sure that is probably the stat that Google keeps looking at in figuring out the benefit vs. loss of forcing names.
Perhaps you can encourage these Anonymous people. Here's a copy and paste I use, it is at the end of my "New mapper - Bad edit" C&P, but I have something similar at then end of several C&Ps. You'll notice that the mention of how to change your name is the last line, so I can easily delete it if they have already changed their name:
